That gOOgle search is good. It also indicates that some of the HF items are available from sources like Amazon at still lower prices. I think that for the reputation and apparent quality of the product, as well as ease of use, I'll go Motive Products.
Typing this I just came up with a possible hack: Use purpose-made A-Dapters (like Motive Products for specific Fords), BUT "Power" the thing with a pump-up garden sprayer. This isn't a big deal, but it seems to me that using the pressure bleeder do both dispense fluid and provide pressure, the disconnect process will always be messy and the master cylinder will always be over-full. Using simply a "pressure tank" sounds like a good idea that gets better with more thought. Am I missing something?
